Application filed February 27, 1812. Serial No. 680,223. 7

To all whom it may concern Be it known that I, IIAYES GADmE, a citizenof the United States, residing at Wellington, in the county of Sumnerand State of Kansas, have invented a new and useful axes to guide themachine,- the steering 'mechanism being .operable by the person ridingon the cultivator and being unaffected by the actuation of the balancingmechanism. I

Another object is to provide improved means whereby the cultivator,sliovels can be shifted vertically within the machine, said shovelsbeing disposed n groups or gangs and each gangflpeing shiftable eitherwith or independently, of the next adjoiin ing 11.

A further object is to provide means whereby the cultivator blades orshovels can be shifted transversely of the machine so as to adjust themrelative to the rows.

Another object is to provide a lock iiicluding means whereby the cultvator blades are automatically unlocked prior to their transverseadjustment, the means for shifting or transversely adjusting the bladesbe ing employed for actuating the lock to hold said blades in anyposition to which they may be adjusted. I

With the foregoing and other ob ects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be madewithin thescope of What is claimed, withoutdeparting from the spirit of theinvention.

In the accompanying drawings the preferred form ofthe invention has beenshown. In said drawings :-Figu're l is a plan view of the machine. Fig.2 is a rcar elevation thereof. Fig. 3 is a side elevation, one of thesupporting wheels being removed Specification of Letters Patent,

Fig. '10 is a Viewpartly in side elevation and partly in section of one of the gangoperating levers. Fig. 11 is a side elevation thereof, the segment ofthe Fig. 12 is a sec- Referring to the figures by characters ofreference 1 and 2 designate front-and rear parallel frame members eachhaving depending parallcl arms 3 at its ends. The side of the machineare connected by a guide member 4 parallel with the plane occupied bythe frame members 1 and 2. Another guide member 5 is secured to theupper end portions of the arms 3 at each side of the machine and isparallel with the guide member 4 thereunder. As shown in the drawingsguide member and it is to be understood that the member 4 is to besimilarly slotted. I The two guide members 4 and-5 at each side of themachine are of like construction with the exception that the upper guidemember 5 is provided,

at each end, with an enlargement .6 fitting snugly against the angleportions of the frame members 1 and 2, where the arms 3 extenddownwardly through the enlarge being attached to the frame members 1 and2 by U-holts 7 or the like straddling the frame members.

Thus it will be seen that the guide members 5 arefixedly connected tothe frame members l and 2 as well as to the arms 8 and,

therefore, rotation of the frame members-is prevented and the arms 3 Anysuitable means may be employed for securing the lower guide members atto the arms 3. Draft beams 8 are mounted on the frame members 1 and 2'and carry a cross beam 9' to which is connected draft mecha-' 5 isslotted longitudinally" are maintained at all times in fixed relation toeach other.

elevation nisin indicated generally at 10. The beams S constituteadditional means for holding the frame members 1 and 2 in properrelation to each other. An additional beam 18 5 is fixedly ecured to themembers 1 and 2 at points equidistant from the beams 8 and extendsrearwardly from the frame member 2 so as to form an efiicient supportfor the seat 19. A tie strip 20 connects the front 10 end of this beam18 to the middle portion of the transverse draft beam 9. Brackets 21 aremounted on the beam 18 and a longitudinally extending shaft 22 isjournaled in these brackets, said shaft being bent to form an elongatedcrank 23. Oppositely extending arms 24: are formed on or secured toshaft 22 close to one end of the crank 23 and each arm is connected, bymeans of a downwardly extending link 25, to a foot lever 26 whichextends rearwardly to a point where it can be conveniently reached andactuated by a person occupying the seat 19. Thus it will be seen thatupon the depression of one of the levers 26, one of the 25 arms 24 willbe pulled downwardly and the shaft 22 rotated so as to swing crank 23toward one side 01. the machine whereas, when the-other lever 26 isdepressed, crank '23 will be swung toward the other side of the machine.

Mounted for sliding movement in the slot in each of the guide members 5is a block 27 having ears 28 at the sides thereof and spaced. therefromto receive the side portions of the guide member 5, as illustrated inFig. 7. Anti-friction wheels 29 are journaled in the spaces between theblock 27 and its ears 28 and constitute supports for the member 5.Another block 30 similar in all respects to the block 27 is mountedwithin each of the lower slotted members i and extending through theseupper and lower blocks 27 and 30 are stems 31 provided, at their lowerends, with spindles 32 arranged at right angles thereto. These stems 31are prevent-' ed from moving domiwardly within the blocks 27 and 30 bycollars secured to the stems and bearing downwardly on the lower blocks30. Upward l'l'lOVQIl'lQllil of the stems 5G 31 within the blocks isprevented by collars 34: bearing upwardly against the blocks, as shownin 1' 2. Supporting wheels are journaled on the spindles 32. is to beunderstood that the stems 31 are adapted to rotate'within the blocks 27and 30. Arms 36 are fixedly connected to the upper ends of the stemsthese arms being parallel at all times and said arms are pivotallyconnected to a cross rod 37 which is parallel with the members 1 and 2and extends above the crank 23.

whirl'r the crank 23 extends. Ti 7 t n it A hanger 38 extends down-'wardly from the middle portion of the rod.

be seen that when crank 23 is swung toward one side, hanger 3S and rod3? will be shifted therewith, thereby causing the arms 36 to swinglaterally and to rotate the stems 31. The two supporting wheels 35 willthus be turned so as to steer the machine in the desired direction.

The balancing mechanism constituting a part of this invention includes arock shalt 10 journaled on the beams 8 close to the transverse draftbeam 9 and this rock shaft is provided, at its ends, with (lOWTlWilldlYextending arms 1-1. Each of these arms has rearwardly diverging links 42and 4:3 pivotally' connected to it, the upper link being pivotallyconnected. to the upper block 27 at one side of the machine, while theother link &3, is pivotally connected to the lower block 80. An arm 44extends upwardly from the shaft 40 adjacent the center thereof and isconnected, as by means of a rod 41-5, to a lever 46 fulcrumcd on thebeam 18 where it can be easily reached by the occupant of the seat 19.This lever is provided with a toothed segment 17 adapted to be engagedby a pawl carried by the lever and whereby the lever can be locked inany position to which it may be adjusted. The said pawl been indicatedgenerally at -18 in Fig. From the foregoing it will be seen that whenlever i6 is shifted in one direction, shaft 4-0 will be rotated so as tocause arms 41 to pull forwardly on the links .2 and .13. As these linksare connected to the blocks 27 and 30 carried by the wheel supportmlstems 31, it will be seen that this action of the shaft 40 will causethe said shaft 40, and the structure made up OIl the frame men:- how 1and 2, the beams 8 and 18. and the parts mounted thereon, to moverem-\varrlly, thereby shifting the center of gravity. When the movementof lever 4-6 is reversed, the operation will be reversed so lhut thecenter of gravity will be shifted forwardly relative to the supportingwheels 35. Mounted on the frame members 1 and at opposite sides of thecentral beam 18 are carriages d9. Each of these.carriagnis consists ofparallel side members 50 connected by cross strips 51 and 52. GroovedSll[')])011- ing wheels 53 are journaled in the end portions of the sidestrips 50 and bear downwardly on the frame members 1, and 2. Guide rods5 1 extend transversely of the machine above and parallel with the framemembers 1 and 2 and are supported at their ends by brackets 55. Theserods engage the upper portions of the rollers 53 so as to prevent saidrollers and the carriages from becoming displaced relative to the framemembers 1 and 2.

A rack bar 56 cxlmirled from the rear end of each beam 9 to the rear endof the radium-sol; guide in- .--v- 5, this; rack bar being parallel withthe rear frame member 2 and being extended under the rear portion of theadjacent frame 49.

Mounted on the rear end portion of one of the side members of eachcarriage 49 s an inverted U-shaped guide 57 in which 1s formed a slot58. A locking pin 59 is mounted to slide within this slot 58 and itslower end is held normally in engagement with the rack bar 56, by meansof a spring 60 which is coiled about the pin 59 and bears at one endagainst the guide 57 and at its other end against a pin 61 or the likeextending from the pin. y

A yoke 62 is pivotally mounted at its center upon the upper portion ofthe pin 59 and extends downwardly so as to straddle the guide 57 saidyoke having outstanding feet 63 which are slidably mounted withinslotted guides 64 upstanding from the side strips 50 of the carriage. Arod 65 is pivotally connected to the yoke 62 at a point above the pin 59and is also pivotally connected'to an arm 66 extending radially from therear end of a rock shaft 67 journaled on one side of the beam 18. Ahandle 68 extends rearwardly from the arm 66 to a point where it can beconveniently grasped by the occupant of the seat 19. Another arm 69 ex--tends radially from the forward end of the shaft 67 and is connected, asby means of a link 70, to abracket 71 secured on the front end of theside strips 50 of the carriage.

' It will be apparent, by referring particularly to Figs. 5 and 6, thatspring 60 holds the spring 59 normally in engagement with the rack 56and, when the pin is thus disposed, the yoke 62 is located in asubstantially upright position. When shaft'67 is rotated in onedirection by means of handle 68, either pulls or pushes through link 65,upon the upperend portion of yoke 62. The yoke is thus caused to tiltupon one of its legs 63 while the other leg is elevated within one ofthe guides 64. The yoke will thus pull on the pin 59 and lift its lowerend out of engagement with the rack 56. This operation takes placeduring the.first portion of the movement of shaft 67. During furthermove; ment of said shaft the foot at the elevated side of the yoke 62comes into contact with i the upper wall of the slot in guide 64 and isthus held against further movement in an upward direction. Consequentlythe yoke will be shifted laterallyby the link and will cause thecarriage 49 to travel along the frame members land 2, the rollers 53serving to reduce friction to the minimum. As soon as the carriage hasbeen shifted transversely of the machine in this manner. until it hasreached a predetermined position, handle 68'can be released whereuponspring 60 will return all of the parts to their initial positions, pin59 moving into engagement with the rack 56 and thus locking the carriageagainst further movement. By connecting shaft 67'at its two ends to thecarriage 49 at the front and rear ends of the carriage, it will be seenthat said carriage will be held parallel with the beams 8 while beingshifted. The position of the pin 59 and the parts adjacent thereto whenshifted out of normal position, has been indicated by dotted lines inFig. 5.

Extendingg" rearwardly from the transyerse draft beam .9 are brackets-72 supportmg a cross bar 73 which is preferably bolted or otherwisesecured to the beams 8, as indicated at 74. Mounted on this bar in frontof each carriage 49 is a pair of heads 75 each of which includes spacedears 76 mounted for rotation on the bar 73. Two pairs of eyes 77 areformed on the heads 75, one

eye of each pair being disposed above the other eye and spacedtherefrom. A collar 78 is mounted on bar 73 between the ears 76 and isadapted to be held against movement on the bar 73 by means of a setscrew 79 or the like. Each pair of eyes 77 has a stem 80 mounted forrotation therein and .said stem is held against longitudinal move mentrelative to the eyes, by means of a collar 81 which is secured to thestem by a set screw 82 or the like. at the upper end of a hanger 83 andthe lower end of the hanger is provided with an upstanding stem 84. Thisupstanding stem extends through spaced ears 85-connected to the frontendof a cultivator beam 86. Said ears are engaged by the stems S4: of bothhangers 83 connected to the heads 75 in front of the cultivator beam, aswill be apparent by referring to Fig. 1, and the ears 85 are heldagainst movement along the stems 84 by collars 87 which are interposedbetween the ears and are fastened to the stems by set screws 88 or thelike. As shown in Fig. l the distance between the stems 84 is the sameas the distance between the stems 80 and the hangers 83 are thereforeparallel and form, with the heads 75 and the ears 85, a parallelogramwhich permits the ears 85 to shift laterally relative to heads 7 5 butcauses said earsto remain always substantially parallel with the bar 73.The cultivator beam 86 is preferably formed of a length of metal havingits rear end portion offset laterally so as to be engaged by thestandard 89 of the rear cultivator blade 90 of the gang connected to thebeam 86. Another cultivator standard 91 is-connected to the beam 86 infront of but to one side of the path of the blade 90. A metal strip 92is secured to the rear end of the strip 86 andiextends alongside of therear portion of said strip 86 and is then ofiset, at 93, where it isengaged by another standard 9% Stem 80, is formed nected, as by means ofa rod 104, to a spring acenoae of a cultivator blade. Thus it will beseen that three standards are connected to the beam, said standardsbeing out of alinement. It is to be understood of course that anydesired number of standards may be connected to the beam and thesestandards can be disposed in any relation desired.

A guide ear 95 is extended laterally from the strip 86 and is slidablymounted on a' guide rod 96 suspended from one of the side strips 50 ofthe carriage 4:9 above the beam. The cross strip 51 on each carriage hastwo alining shafts .97 journaled thereon, each shaft being provided atits outer end with a radial arm 98 connected, by means of a link 99, toone of the beams 80 under the carriage. A forked lever 100 is looselymounted on the two shafts 97 close to the adjoining ends thereof andstraddles a toothed segment 101 which is fixedly mounted on the carriage19. A gear 102 is journaled within the forked lever 100 and meshes withthe segment 101, this gear being normally engaged by a toothed slide orpawl 103 mounted in the lever and conpressed lever 105. Pawl 103 servesto hold gear 102 against rotation and as this gear is constantly inmeshwith segment 101, it will be apparent that lever 100 is normallyheld against movement about the shafts 97. A toothed segment 106 issecured to each side of lever 100 and is concentric with the shafts 97.Levers 107 are fixedlyconnected to the respective shafts 97 and close tothe lever 100 and each of these levers 107 carries a-spring pressed pawl108 normally engaging the adjacent segment 100. Thus it will be seenthat levers 107, pawls 108 and segments 100 serve to normally lock thelever 100 to the two shafts 07. ll' ith. the parts thus connected itwill be seen that, by shifting lever105 so as to raise the slidev .13,gear 102 will be released and lover 100 can then be swung about itsfulcrum so as to cause the two levers-107, which are locked thereto, torotate the shafts 97 simultaneously. The arms 98 extending from theseshafts will, therefore, 'shift the links 90 so as to raise or lower thebeams 86. Should it be desired to shift one of the beams below carriage49 independently of the other beam, the lever 107 controllingsaid beamreleased from the segment 106 adjacent thereto and shifted independentlyof lever 100 hen the desired adjustment has been obtained said lever 107can be locked to lever 100 by means of pawl 10% and ment 106.

It will be apparent that by using a machine such as herein.described, "Hor ir supporting structure shifted 'Wardly or rearwardly relative to theaxis rotation of thesuppcrting wheels and with tee or such movement willnot interfere steering mechanism. Furthermore the two carriages can beshifted toward or from each other so as to move the cultivator bladestoward or away from the rows or so as to adjust them to rows atdifferent distances apart.
